18650 lithium ion battery has high safety performance, no explosion, no burning; non-toxic, no pollution, RoHS trademark certification; all kinds of safety performance in one go, the cycle number is more than 500 times; in order to prevent battery short circuit phenomenon, 18650 lithium ion battery The positive and negative poles are separated. Therefore, the possibility of short-circuit phenomenon has been reduced to [extreme]. A protective board can be installed to prevent overcharge and overdischarge of the battery, which can also extend the service life of the battery.

18650 lithium ion batteries can be used in notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras and other electronic equipment.

As smart phones and laptops become more and more widely used, it is obvious that it will be a cocoon if this continues, so now everyone has basically unified the standard, a charger/cable can charge electrical appliances of different brands and properties. Charging is convenient, and a problem that users should pay attention to is to try to keep the battery with the power of normal use at all times. Under normal circumstances, when the battery is too low, both the mobile phone and the laptop will give a reminder. At this time, you need to recharge the battery in time. Although the battery is too low will not cause a direct safety accident, but overuse will cause damage to the battery structure over time. .

Lithium-ion battery charging is divided into two stages; first, constant current charging, that is, the current is constant, and the voltage of the lithium-ion battery gradually increases with the charging process. According to the above specifications, it is generally charged with a current of 0.2c (c is the nominal capacity and current of the battery, 0.2c is 200ma). When the battery voltage is close to the full voltage of 2v, the constant current charge will be changed to a constant voltage charge. This process is about five hours. Constant voltage charging, that is, a certain voltage, as the saturation of the wire deepens, the current gradually decreases. According to the specification, when the current drops to 0.01C, that is, 10mA, charging is deemed to be terminated. After this process and the constant current charging time are added, the total charging time should not exceed 8 hours.

Voltage platform is an important indicator of battery energy density and determines the basic performance and cost of the battery. Therefore, the selection of battery materials is of great significance. The higher the voltage platform, the greater the specific capacity, and certainly the same size, weight, and even the same ampere-hour battery, the higher the voltage platform of the ternary material lithium battery has a longer range. The voltage platform of the ternary material is significantly higher than that of lithium iron phosphate, the high line can reach 2 volts, and the discharge platform can reach 6 or 7 volts.

Laptop computers, handheld walkie-talkies, portable disc players, instrumentation equipment, audio equipment, model airplanes, laptop computers, digital cameras, lighting equipment, children’s toy company products, pneumatic tools and other electronic equipment, as an important combination of the lithium-ion battery family In the early years, 18650 batteries were widely used in consumer electronic products. In recent years, with the strong rise of new energy electric vehicles, 18650 batteries have also begun to be used in the new energy electric vehicle industry.

Cylindrical lithium battery and square lithium battery comparison: battery shape: square size can be designed arbitrarily, but cylindrical batteries can not be compared. Rate characteristics: the process limitation of the cylindrical battery welding multi-terminal ear, the rate characteristic is slightly worse than that of the square multi-terminal battery. Discharge platform: The lithium battery adopts the same positive and negative materials and electrolyte. Theoretically, the discharge platform should be the same, but the discharge platform in the square lithium battery is slightly higher. Product quality: The manufacturing process of the cylindrical battery is relatively mature, the pole piece has a low probability of secondary slitting defects, and the maturity and automation of the winding process are relatively high. The lamination process is currently still semi-manual, which is important for the quality of the battery. Have adverse effects.
